At an appropriate place, two upstanding members 58 may be secured at the two sides of the table l2 carrying a pivot pin [9, on which may rock an appropriate stapling head, generally inl dicatedby the numeral 28. The upstanding supports 18, at the two sides of the table l2, and the pivot pin'ie between them, form a bridge over the sausage i5, permitting an easy movement of "the same thereunder in its trough M.

The stapling head 29 may be of any appropri ate construction, well-known in the art, and in the embodiment shown in Fig. l, the main operative features of one of such well-known maof the machine.

round the sausage 5 at the portion thereof chines are.shown,'adapted for the present purpose, the machine in which the constructional details of said head 26 are embodied being known in the trade as the Hotchkiss, manufactured by the E. H. Hotchkiss Co. at Norwalk, Conn, and patented on'D'ecember 10, 1913, No. 1,767,285, in which patent said features are described.

Said stapling head consistsoi a'generally ver tically placed hollow casting 21, being pivoted on the pin 19 by an e longated substantially horizontal branch 2-2- thereof. In said branch are slidingly housed the wellknown angular wire wher'e the-propelling is to be executed, the lower termination 43a ofsaid arm being connected to an appropriate pin 460. on said arcuate member by a link member 41. A plurality of forwardly projecting spring fingers 48 are secured in the arcuate member 46, having inward bends 49 at their free ends. :These resilient bends wiil engage ,the sausage [5 in one position of the link 41 and disengage it in anotherposition thereof, as

will be more fully explained presently;

The arcuate member ,46 is continued in two downwardly turned branches 4%, carrying a staples 23 (Figs. 1 and 4), being urged forwardly by a slidinghead 24, secured on a spring :25, coiled V in a housing 26.;

, Ablocl; 21 is provided in thelower part of the hollow casting 2i and the stapling wire blanks are pressed against the front-face 2B of said bloch.

' Aslot Z-Q, permitting the downward exitof the first one of said staples 23, is provided in the lower end of the casting 2| and ablade is arranged, movableupwardly-and downwardly, over said blank andsaid slot 291.

Flat. springs 315aarranged at the two-sides of the table 12 and engaging the underside of said horizontal branch 22, are normally urging said branch and the head iLfwitn their associate parts, in an upward direction.

A counterstapling head 35 is provided, in axiali of thedevice; the upper stapling head or cast ing 2i and the counter head 35 are'interconnected by the link mechanism 31,- 36 in such a manner that they simultaneously will. move towards each other, or away fromone another, as will be understood. Arm orlink 38 isrockable on a stationary pin'3 8a,'and theleit hand side there} F "Ofll's provided with a slot 382; in which may slide pin 350. secured on a downward extension 35b of part'fifi, and slidable, therewith... I

The lower or counterstaplinghead 3.5 may have 1 a forming groove or recess3-9 in its upper surface,

axially alined with the slot, to form thenecessary staple loops 23d from the staples 23 when the same; are pressed thereinto, as it .is wellknown-in such machines.

. In the embodiment of a stapling machine used pin 59 underneath the table l2 of the machine, and .rollers 5i may be arranged on the. pin .58 thereby to facilitate theforward and backward movement of the arcuate member .46, as will be described hereinafter. V

A pivoted arm or red 52 is secured to thep-in 42a of the-crank 42, said rod 52 having a central slot "52a, and a pivoted arm or rod 53 is rockably secured to a pin 54 on thearm 4-3 through the parts 51 and 53c (Fig. I), the inner end of said rod 53 carrying a pin 53a slidable the slot 52a, these parts provid'ing an appropriate driving connection between the shaft 40 and the arm 43,

it being understood that rod 53is behind rod 52.

(Fig.6). a g V The use andoperat'ion of my machine are as follows;

theh'ead 21, in the embodik the drawing, said counter head 35 being slidable in a socket 36in the forward leg crank 42 thereon, rotate in an. anti clockwise in'myin-vention, and indicated'in Fig. 1, ashaf't Qt maybe arranged over. the plunger 3l,fsaid ."The long sausage T5, coming from the filling or stuffing machinawill belplaced into the trough 14 an'dpulled forwardly until its forward end is engaged by the spring fingers '58, and upon the rorward movement of the swinging arm 43, said fingers will move the sausage 15 in the trough l4 for'wa'rdlywith the distance of the swin of the arm 43, as will be explained presently.

Fig. 1 illustrates my machine in the position right after such a movingof the sausage l5, and when the'next stapling operation isju'st beginning. i i

1 The roller 31a on the upper end oi'the plunger 31 isenea'sing, the-narrowest'portion of the cam H, that is, its' hub Ma, so that springs '34a ;are allowed to push thewhole stapling head 21 into its uppermost open position, and coiled spring 32 will push the plunger. 3| also into'fitshighest position. Wh'enthe stapling head '2! is in i'tsdescribed highest position, thecounter stapling head '35 will be in its lowest position, as indicated, through the'actionpr the link mechanism 31,33, as Will be ObViollSfalld it Will b'Sh that the sausage 15. is new entirely .fr-ee betweei'i'theheads "2"] and 35.

. and during this time thesausage "l5 will be tightly secured by the st'a'plingheads! I;and,35; while; at thelsame time, arm 43 m foremost position, shown by full lines inFig. 1,.

will "swing' from its dottedlines in said Figure 1. The position 01' q pin 46a, the Iength'of the arm 43,; and the length :of the link member" may bearrang'ed in such a manner that, upon thereturn of thearm 43,said link "will be thrownto the left side of the ar'cuate member was against :its forward position,

shown; in the drawing," and "in such a position spring fingers 48' .may" be lifted 1 somewhat 11pwardly and they, may idly :ride inla backward directionover thesausage I5. As will beseen ln Fig. 5; arcuate member 46 may begmade of two halves having central upstanding extensions16e set closely together and joined by the pivotpin 46a for the link member 41. Said link member chineto change the :swing of the arm 43.

will engage the sausage 15,- their depressions being pressed into the soft body thereof toa desired degree, so thatthe'forward movement of the arm '43 will cause the sausage l'5toslide in thetrough l4 to a distance determined by -the swing of said arm43, andaajnew stapling oper'ation may start, as describedhereinbefore, atsuch a distance from the one just finished. 3

d If ltviS desiredto change the distancethrough whichuthe sausage l5 will bemoved, that is the length of the individual'frankfurter, appropriate regulating means may, be provided in my maa means, in the form of turnbuckle 51-; is indicated in Fig. 1, its operation being obvious.

*Spring means; 58 mayalso be applied, forwardly and rearwardly onthe alienate member 46 bywany appropriate means, sliding on the bed l2, to steady; themotion of said arcuate member and t'oj prevent undue pitessure and impression of; the spring] armsflaqon the sausage, or a too easyliftingyof thernfrom the same. i

y I may remark that the staplingloop 23oz preferably is made somewhat "loose and not very tight on .the constricted portion 15a of the Sall sagel5 .q; g 1 1 It is also obvious that means may be provided whereby the operation of the machine 1may be m stopped while Ianew long sausage i5 is being to its rearmost position Ivy-indicated by the fed thereinto, or at any time when it is desired to prevent the formation may embody "an, appropriate lcoupling between the, shaft All and the electric motor, or other tion ofthe shaft 40 and the operation of my linkingdevicejthe operator of the machine may is made of two identical parts between which are arranged said extensions 460, at the one side, and
